About this exam

The ASQ Certified Six Sigma Yellow Belt (CSSYB) is an entry-level credential for people who support improvement work rather than lead it. ASQ states the certification has no experience or education requirements, and that it is aimed at candidates who have a small role, interest, or need to develop foundational knowledge - team members, support functions, and anyone new to Six Sigma vocabulary.

The exam samples the full DMAIC arc at a foundational level: Six Sigma and the organization, then Define, Measure, Analyze, Improve, and Control. Expect concepts, terminology, and basic tool application rather than deep statistical derivation. All ASQ exams are open book, references must be bound, and computer-based sessions include an on-screen basic scientific calculator.

Delivery runs through Prometric. Computer-based candidates receive an eligibility email one to two business days after approval; paper-based and translated candidates instead receive a seating letter about two weeks before the exam. ASQ lists application deadlines of December 7, 2026 and February 8, 2027 on its certification page.

Preparation is self-directed. ASQ sells a handbook ($150 list / $105 member), e-learning ($424 / $324), a question bank ($119 / $109), a study guide ($60 / $42), and the Quincy study assistant ($79 / $59).

What you'll study

Common questions

About CSSYB preparation

Do I need work experience or a degree to sit for the CSSYB exam?

No. ASQ states the Certified Six Sigma Yellow Belt has no experience or education requirements. It is aimed at candidates who have a small role, interest, or need to develop foundational knowledge, which makes it a fit for team members, support staff, and people new to improvement work rather than experienced practitioners who lead projects.

How is the exam delivered, and does that change my scheduling steps?

There are two routes. For computer-based testing through Prometric, you receive an eligibility email one to two business days after your approval notification, containing scheduling instructions. For paper-based or translated exams you get no eligibility email - instead a seating letter with your exam date, time, and location arrives roughly two weeks before the exam.

Is the exam open book, and what reference materials can I bring?

Yes, all ASQ exams are open book. Reference materials, including notes, must be bound and stay bound - stitching, glue, ring binders, spiral binders, plastic snap binders, brads, or screw posts. Hand-stapled documents, unbound notes, blank writing tablets, and slide or wheel charts are prohibited. The test center administrator inspects references before you enter.

Can I reschedule my appointment, and what does it cost?

You must change your date or time at least five days before your appointment, using Prometric's Reschedule/Cancel option on its website or its automated voice response system. There is a $130 fee for changing an appointment. Failure to appear for your scheduled appointment results in loss of all application fees.

What happens if I arrive late on exam day?

Plan to arrive 30 minutes before your scheduled appointment to allow time for check-in procedures. If you are late in arriving, you will not be allowed to test and you will forfeit your exam fee. Build the buffer into your travel plan rather than treating the appointment time as your arrival time.

How long is the exam and how many questions does it contain?

ASQ's CSSYB page does not publish a question count, time limit, or passing score, so verify any specific figure with ASQ before you book. What the page does confirm: the exam is multiple-choice, delivered by ASQ's testing partner Prometric, and open book with an on-screen basic scientific calculator.

What should I study first, and which preparation resources matter most?

Work the phases in order - fundamentals, then Define, Measure, Analyze, Improve, Control - because later phases assume earlier vocabulary. ASQ lists a handbook ($150 list, $105 member), e-learning ($424/$324), question bank ($119/$109), study guide ($60/$42), and the Quincy study assistant ($79/$59). Read the guide first, then drill the question bank.

Where do candidates most often get tripped up in the application process?

Two choke points. Application review takes one to two business days online but three to five for hardcopy, so paper applications compress your scheduling runway. Also, if ASQ determines you do not meet requirements, your refund is reduced by a $130 processing fee. Submit online, and bring a government-issued photo ID whose name matches your application exactly.

If I fail, can I retake the exam - and what does a retake cost?

ASQ's CSSYB page does not state a retake policy or retake fee, so confirm directly with ASQ before test day. It does confirm the cost of missing: no-shows forfeit all application fees, and rescheduling runs $130. Choose a realistic exam date you can prepare for rather than relying on a cheap second attempt.
